ABSTRACT:
A quick connectable manually separable fluid conduit coupling includes a tubular male member having a tapered forward portion including a sealable bearing surface, and a radially inwardly directed shoulder adjacent the rearward part of the forward portion and adjoining a recessed circumference. A female sleeve includes plural stiff, yet resilient, substantially parallel, circumferentially disposed fingers. Radially inwardly extending lips on the fingers have latching surfaces for automatically snapping behind and grasping the shoulder of the male member upon assembly, and further have wedge surfaces radially outwardly movable by axial motion of the tapered forward portion of the male member into the female sleeve during assembly.
